Such allows the fastener to be shifted right angles to form a handle or catch by up and down, and consequently the cuff to be which the slide may be easily drawn back, as more or less exposed beyond the coat-sleeve, required, for attaching and detaching a cuff. as the taste or convenience of the wearer may The slide is further guided by lips A A dictate.

Thetwot-hicknesses back. hen it is desired to disengage the of the cuff are shown in section. Fi 6 is a fastener, the wearer touches the handle 13,

and pressing backward thereon with su fficient force moves the slide to the extreme backward position which it occupied at first. Now, the device can be easily disengaged by the reverse movement to that by which it was in- ,serted.

The limit of the backward movement of the slide may be determined by the handle B striking the clasp M. The position of the extreme backward motion should be accurately determined. It should be such that the point will lie in or very slightly protruding beyond the offset A. In the forward or outward movement of the slide it is not material at what precise point it comes to rest. I avail myself of this fact to insure a high degree of friction to aid in holding it in its extreme outward position. This is effected by making the body of slide B very slightly tapered and forming the body A, or rather thespace within the lips A correspondingly tapered, the taper being such that the slide when it has been thrust forward to about the right position is arrested by wedging within the lips. Care being taken by suitable dies or otherwise to makethe taper of each very moderate, the frictional force with which the slide may be held is Very great. In moving the slide backward or forward it moves easily in all parts of the motion, except while near the outward position, when it is subject to the extreme friction.

WVith the exception of the long-approved clasp M, there are no working parts, except the simple straight slide above described working between the lips and extending through the hole in the body. The device is strong, easily worked, and holds reliably. It does not abrade the button-holes or expose them to any serious wear, either While in use or while being inserted or removed.

Modifications maybe made without departing from the principle or sacrificing the advantages of the invention. Instead of the continuous lips A one or more short narrow wings may be formed on the edge of the body,

and properly bent over like the lips A In such case a pair of such narrow wings may be formed on the bodynear the offset A, ready to guide the slide if, through any accident or malformation, the slide should be drawn quite out through the hole a, and the rear end of the slide may be provided with a pair of corresponding narrow wings, which maybe bent backward and engage around the edge of the body. Fig. 6 shows such a modification. I prefer the form first shown.

I claim as my invention- 1. In a cuff-fastener, the body A, having an offset A and point or extension A substant-ially parallel with the part A, adapted to be thrust partially through the button-holes of a cuff and havinga clasp Mon the rear end, in combination with a slide B and suitable guiding means therefor, adapted when thrust forward to present its point parallel with the point upon the opposite side of the cuff, and thus firmly lock the device to the cuff while the clasp holds the device to the shirt-sleeve, all substantially as herein specified.

2. In a cuff-fastener, the body A, with offset A, having hole a, point A lips A and pivot A in combination with the clasp M and with the slide B, guided within the lips A and playing through the hole a and having an operating catch or handle B, all arranged to serve substantially as herein specified.

3. The slide B, formed tapering, as described, in combination with the body A, having the hole a, and lips A adapted to arrest the slide by friction at the outward extreme of its movement, and having the offset A, point A and clasp M, all arranged for joint operation relatively to each other and to a cuff and sleeve, substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
